[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Embodiment 1

[0026] Combined with Figure 1-3 In order to solve the above technical problems, the technical solution provided by the utility model is: a high-efficiency water mist dust removal device, comprising a separation tank 1, an air intake pipe 2 is connected to one side of the bottom of the separation tank 1, a plurality of axial flow fans 11 are connected to the top of the separation tank 1, a water pipe 9 is connected to the top of the separation tank 1, a No. 1 water pump 10 is connected to the water pipe 9, so that the water in the water tank 12 is transported to the diversion pipe 7 through the water pipe 9, one end of the water pipe 9 extends to one side of the separation tank 1 and is connected to the water tank 12, a water supply pipe 13 is connected to one side of the top of the water tank 12 for adding water to the water tank 12, and one end of the water pipe 9 extends to the bottom of the water tank 12.

[0027] The separation tank 1 is used to provide a place for water mist dust removal. The gas to be dusted is transported to the separation tank 1 through the air inlet pipe 2. The axial flow fan 11 provides power for the gas entering the separation tank 1 to discharge upward. The water mist sprayed by the atomizing nozzle 8 is used for gas water mist dust removal. The water tank 12 provides temporary storage for water used for water mist dust removal. The atomizing nozzle 8 and the water tank 12 are connected by a water pipe 9. The area sprayed by the axial flow fan 11 and the atomizing nozzle 8 needs to maintain a certain height, and the operating speed of the axial flow fan 11 needs to be reasonably set according to the on-site application conditions to prevent the water mist used for dust removal and separation from being drawn out from the exhaust at the top of the device, or the gas entering through the air inlet pipe 2 cannot completely form an ascending airflow in the separation tank 1, thereby affecting the effect of water mist dust removal.

[0028] Embodiment 2

[0029] Combined with Figure 1-4 And attached Figure 6 ,7 A transmission shaft 4 is rotatably connected upwardly in the separation tank 1. A No. 1 motor 5 matched with the transmission shaft 4 is connected upwardly in the separation tank 1 to provide power for the rotation of the transmission shaft 4. A support frame 3 matched with the No. 1 motor 5 is connected in the separation tank 1 to fix and support the No. 1 motor 5 and the support 6. A shunt pipe 7 is connected above the support 6. Atomizing nozzles 8 are connected to each end of the shunt pipe 7. The top of the shunt pipe 7 is rotatably connected to the water pipe 9 through a rotating joint.

[0030] The water delivered by the water pipe 9 is divided into multiple water channels through the shunt pipe 7 and supplied to each atomizing nozzle 8. The number of the atomizing nozzles 8 is set accordingly according to the number of ends of the shunt pipe 7. The transmission shaft 4 rotates to drive the support 6 and each atomizing nozzle 8 to rotate in the separation tank 1, so that the water mist can cover the rising gas more widely and capture the dust in the gas more effectively.

[0031] Embodiment 3

[0032] Combined with Figure 1-5 A recovery tank 14 is connected to the bottom of the separation tank 1, and a heating coil 15 is connected to the recovery tank 14. A No. 2 water pump 16 is connected to the heating coil 15 to make the hot water or hot steam in the heating elbow flow. A stirring shaft 17 is connected to the recovery tank 14 to rotate upward. A No. 2 motor 19 that cooperates with the stirring shaft 17 is connected to the bottom of the recovery tank 14 to provide power for the rotation of the stirring shaft 17. A plurality of blades 18 are connected to the stirring shaft 17. A steam pipe 20 is connected between the recovery tank 14 and the top of the water tank 12. An air pump 21 is connected to the steam pipe 20 to transport the water vapor in the recovery tank 14 to the water tank 12 through the steam pipe 20. One end of the steam pipe 20 extends to the bottom of the water tank 12. A sewage pipe 22 is connected to the bottom of the recovery tank 14. A solenoid valve 23 is connected to the sewage pipe 22. When opened, the waste water in the recovery tank 14 can be discharged.

[0033] The dust-containing water flowing down from the upper separation tank 1 is received by the recovery tank 14, and the water is heated by the heating coil 15 to evaporate. The stirring shaft 17 drives the blades 18 to stir the water in the tank to facilitate faster evaporation. In this way, most of the water used for water mist dust removal forms water vapor, is separated from the dust, and returns to the water tank 12 through the steam pipe 20 for continued use. This makes the wastewater treatment after water mist dust removal faster, more effective and more environmentally friendly. The water vapor returned to the water tank 12 is less than the water in the water tank 12, so it can quickly return to liquid state without affecting the original water in the water tank 12. The hot water or hot steam in the heating coil 15 circulates, and its two ends are connected to corresponding heating equipment, such as the waste heat recovery mechanism generated after the production of certain equipment in the factory production process. The supplied waste heat needs to reach a suitable temperature value or above so that the water at room temperature can effectively undergo a relatively fast evaporation reaction.

[0034] When the utility model is implemented in practice, when the device is used for gas water mist dust removal, it is no different from the use of most water mist dust removal equipment. The device enters the dust removal tank body through the air inlet pipe 2, and the dust-removed gas is discharged from the top of the tank body through the action of the axial flow fan 11. The advantage of this device is that when the gas enters the separation tank 1 and rises under the action of the axial flow fan 11, there are multiple water mist nozzles passing through the dust removal separation point, and they are kept in a rotating state, which makes the sprayed water mist more effectively cover and capture the dust in the gas, and fall into the recovery tank 14 below for temporary storage. When the sewage in the recovery tank 14 reaches a certain level, the heat provided by the heating coil 15 and the action of the stirring mechanism cause a large amount of water in the sewage to form water vapor, and return to the water tank 12 through the steam pipe 20. After cooling into a liquid state, it can continue to be circulated. This makes the wastewater treatment after water mist dust removal simpler, more effective and more environmentally friendly. The remaining sewage after evaporation can be discharged from the sewage pipe 22.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
